Volumetric soil moisture contents have been measured daily between 6 november 2003 and 19 august 2010 with a tdr set-up developed by heimovaara and bouten consisting of six arrays of six sensors between 5 and 73 cm below the soil surface. the six arrays were positioned on the perimeter of a circle with a diameter of 9 m with equal distances. the tdr was calibrated by taking 6 undisturbed soil samp…

Discharge has been measured at three locations. at these locations, measurement weirs have been installed in may 2007 to estimate discharges accurately. a v-notch weir is used to measure the inflow of surface water into the catchment near the wielse kade (qin). trapezoidal rossum weirs have been installed to measure outflow (qout1 and qout2), of which the stage-discharge relations have been obtain…

Groundwater levels at cabauw have been measured since august 2003 in two fields south of the tower. nine piezometers were placed in a row. initially, 6 of those piezometers contained pressure transducers (of the brand keller) to measure levels automatically every 4 hours. on 9 july 2010, the temporal resolution was increased to hourly. several sensors have stopped working since 2003. piezometers t…

Degree days are determined by the effective daily mean temperature (teff). teff is calculated with the daily mean temperature (tg) and the daily mean windspeed (fg). teff = tg - 2/3 * fg. degree days = sum of the days with (max[(14 - teff),0]).

This table contains figures on the actual emissions into the atmosphere in the netherlands by road traffic, including emissions by foreign vehicles. it also presents the average emissions per vehicle-kilometre, the so-called fleet emission factors, are given, expressed in grams per vehicle kilometre. it covers emissions from the combustion of motor fuels and emissions caused by evaporation of fuel…

This table contains figures on the emissions in the netherlands by mobile sources. these are actual emissions in or above the netherlands and on the continental shelf (see paragraph 2). it also contains the emission factors derived from these emissions (in grams of emission per kilogram of consumed fuel). mobile source emissions are caused by the combustion of motor fuels, the evaporation of fuel …
